Do the following to keep just the last 2 kernels on your system, to keep /boot clean
As root perform these steps:
Edit /etc/yum.conf and set the following parameter
installonly_limit=2
This will make your package manager keep just the 2 last kernels on your system(including the one that is running)
Then install yum-utils:
]$ yum install yum-utils
Finally make an oldkernel cleanup:
]$ package-cleanup --oldkernels --count=2
Done. This will erase in a good fashion the old kernels, and, keep just the last 2 of them for the next upgrades.
You can check the space left on the partition by issuing:
]$ df -h
expect something like
Filesystem Size Used Avail Use% Mounted on /dev/mapper/cl_jdoe-root 13G 8.0G 5.1G 62% / devtmpfs 2.0G 0 2.0G 0% /dev tmpfs 2.0G 96K 2.0G 1% /dev/shm tmpfs 2.0G 8.7M 2.0G 1% /run tmpfs 2.0G 0 2.0G 0% /sys/fs/cgroup tmpfs 2.0G 40K 2.0G 1% /tmp /dev/sda1 497M 276M 222M 56% /boot tmpfs 396M 4.0K 396M 1% /run/user/42 tmpfs 396M 48K 396M 1% /run/user/1001
